I like the Bobbi Brown Antique Rose eyeshadow.

This is a godsend for summer cool tones. It has a unique shade that looks like red bean porridge yet is also a muted pink. When applied to the eyelids, it doesn't look out of place and blends well with other colors. It is a product you will reach for often for daily use throughout all four seasons. You can use it as a base and layer other desired accent colors on top, or wear it on its own for a beautiful look. If you have a cool undertone, give this a try!
